Mogadishu Mile mission
As soon as the mission starts, run in front of the last AAV. Jump on the front of it and catch a free ride to the end of the mission. By doing this, you will be on top of it when they speed up and will not have to catch up. This results in you completing the mission faster and easier.

Black Hawk Down mission
Take an assault soldier with a M16 M203 or carbine 15 M203. Shoot them at the top of the broken buildings. You may might kill snipers easily if they are up there.

When playing team tag online, if you have the flag the best place to take it to are as follows:

Black Hawk Down: On the broken buildings, top floor.
Last Defense: Keep running around in the trenches with m203s.
Gasoline Alley: In the garage; on the things that go along the entrance of the garage.
